Can be list stored in dictionary?

Hello,

The title explains if.
Can it be done? If so, then how?

Currently I have this setup

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
        
public class GameGeneration : MonoBehaviour {
        
	// Setup Dictionary for list
	Dictionary<string, List<ModularGameObjects>()> lists = new Dictionary<string, List<ModularGameObjects>()>();
        
	void Awake() {
		// Add stuff to list
		lists.Add ("Platform", new List<ModularGameObjects>());
		lists.Add ("Wall", new List<ModularGameObjects>());
		lists.Add ("Stair", new List<ModularGameObjects>());
	}
}

I think Its possible. you can refer this link :
